The Agent Memory Store That Survived Your Tenant Deletion Because Nobody Owned It
A compliance program is a description of the systems your company had on the day the auditor signed off. The systems your company has today are a different set, and the gap is the surface area of every release that shipped a new persistent store between then and now. The deletion guarantee you sold your customers is a guarantee against the first set, and the regulator who eventually asks about it will be asking about the second.
The failure mode is not a bug in the deletion code. The deletion code is correct. The saga fans out across every storage system named in the data inventory, calls each one's erasure endpoint, collects a receipt per system, and reports success when every receipt comes back signed. The saga is doing exactly what it was built to do. The problem is that the saga is iterating over a list of storage systems that was true eighteen months ago, and the agent platform team shipped a long-term memory feature six months ago that nobody added to the list.
